The Oxyrhynchus Fish Swallowing the Phallus of Osiris
After the god Osiris was murdered and dismembered by his brother Set, his wife Isis searched the Nile for his remains. She recovered every piece except for his phallus, which had been swallowed by an Oxyrhynchus fish in the river. This event led to the fish becoming sacred and taboo in the region, and Isis was forced to use her magic to fashion a replacement to resurrect her husband.
